New Service Invocations

The first interface is for services that are started anew with each
request. This interface requires the port monitor to first fork() a child process. The child eventually becomes the designated service
by performing an exec(). Before the exec()
happens, the port monitor might take some port monitor-specific action. However,
one action that must occur is the interpretation of the per-service configuration
script, if one is present. This interpretation is done by calling the library
routine doconfig().
